Essential Oils

There are several essential oils that may help to promote hair growth. You can benefit from this effect by adding a couple of drops of your chosen essential oil to a moisturising carrier oil like coconut or shea butter oil, effectively creating a hair growth serum. Alternatively, you could add essential oils to your favourite shampoos or bottled conditioners and use them as normal - we recommend no more than 2 drops per 10 ml of product.

Rosemary Oil

Studies have shown that applying rosemary oil to the scalp over a 6 month period can increase head hair count.[1] Rosemary oil in essential oil form is thought to have anti-inflammatory properties, promote nerve growth and improve circulation, so makes a great hair growth oil.

Pumpkin Seed Oil

Pumpkin seed oil may have a positive impact on hair growth in men. One study found that taking a 400-milligram daily dose of pumpkin seed oil in a capsule form resulted in a 40% increase in hair count after 24 weeks.[2]

Peppermint Oil

Peppermint oil has been found to be effective at increasing dermal thickness, follicle number and follicle depth.[3] Peppermint acts as a vasodilator, improving circulation and potentially preventing some hair loss as a result.



This trace mineral is important for hair tissue growth and repair. Zinc deficiency often results in hair loss as a symptom, but this can be reversed by supplementing the deficiency. Zinc can also help to keep the oil glands around the hair follicle working correctly.[4] You can get zinc from beef, spinach, oysters, pumpkin seeds and lentils, or by supplementing your diet with a zinc tablet.


Being deficient in iron can inhibit haemoglobin production, a protein in red blood cells that carries oxygen, which is necessary for normal hair growth. You can get more iron in your diet by eating more oysters, eggs, red meat, spinach, or lentils.

Vitamin C

As one of the most effective nutrients for growing and strengthening your hair, Vitamin C help build collagen, an important component of hair growth.[5] It is also the only dietary constituent known to promote the absorption of iron other than animal tissue, so getting enough Vitamin C in your diet is essential, for vegans in particular. You can supplement your dietary Vitamin C intake with this chewable vitamin.

Caffeine Shampoo

Caffeine, when applied topically to the hair roots, has been found to stimulate the hair follicles and prolong the growth phase of the hair cycle. Using a shampoo like the Alpecin Caffeine Shampoo is a great way to get caffeine to your scalp, but you could also try the Alpecin Caffeine Liquid if you don’t need a shampoo.


The active ingredient Minoxidil aids blood flow to the hair follicles and increases the follicle size and hair shaft diameter in the process. It’s a great topical treatment for treating hereditary hair loss, but may be beneficial for treating other types of hair loss too.

Regaine, the most popular brand of Minoxidil, comes in Regaine Men’s Foam and Regaine Men’s Solution forms, as well as Women’s Foam and Women’s Solution.


This male-only treatment works by inhibiting the enzyme 5-alpha reductase from converting testosterone to DHT, a hormone known to cause hair thinning and to reduce its growth. You should start to see results from Finasteride after 3 months of taking one tablet per day, and it’s effective at promoting hair regrowth in 90% of men.
